Al Gore, the chairman of Current TV, has accused Sky Italia of refusing to renew Current TV's contract due to a political agenda. Gore claims that his channel was dropped after it hired left wing commentator Keith Olbermann, a directive he says came from News Corp headquarters. Sky Italia have dismissed the claims as "nonsense" and say the decision was a purely commercial one. Steve Hewlett hears from Al Gore and the head of Sky Italia Tom Mockridge. Despite a judge granting an injunction to protect his privacy, thousands of people have made allegations about Ryan Giggs's personal life on Twitter. Does the law need to be re-assessed to take the impact of social networks into account? And can Twitter be held responsible for its millions of users? The Telegraph's Emma Barnett explains where Twitter stands now. Ofcom has upheld a complaint against Press TV, finding the broadcaster in serious breach of the rules. Last year Press TV broadcast a clip of an interview with journalist Maziar Bahari, which was given while he was imprisoned in Iran but the fact that the interview was given under extreme duress was not made clear. Maziar Bahari joins Steve Hewlett to discuss Ofcom's ruling and the future for Press TV in the UK.Producer SIMON TILLOTSON.
